Frozen section evaluation of lymph nodes in Oral squamous cell carcinoma: a retrospective study
The principal indication of performing a frozen section is to obtain a definite immediate diagnosis, on the basis of
which a surgical decision will be made. Immediate diagnosis allows the surgeon to proceed with further therapy
without any delay. A definite immediate diagnosis is said to be dependent on the reliability of frozen sections.
Many authors have carried out frozen section study on soft tissue tumors and lymph node evaluation in different
parts of the body with varying percentages of reliability. However, it appears that lymph node evaluations specifically in oral squamous cell carcinoma cases were not performed, or limited. Hence the present study was undertaken
to determine the reliability of frozen section diagnosis in the lymph nodes of oral squamous cell carcinomas. This
study was performed so that the surgeons would have an intraoperative assessment of the extent of local metastasis
and to determine the adequacy of resection before the wound is closed.
The objectives of the present study are to assess microscopically the frozen section of the palpable and non palpable
lymph nodes of neck for metastasis in patients with squamous cell carcinoma of oral cavity. To compare the micros-
copic features of paraffin embedded lymph node sections with those of frozen sections. To assess the reliability of
frozen section evaluation of cervical lymph nodes in oral squamous cell carcinoma.
The present research work gives 100% accuracy of frozen sections with due care by additional staining to frozen
sections by phloxine methylene blue stain, however cannot be in any way superior to the magnetic resonance imaging, computed tomography, immunoscintigraphy and lymphangioscintigraphy

This study will helpful for researchers to know which article and which author has major contribution and what kind of study he has done in the past 10 years as well as what will be the future scope. The study is first of its kind with reference to this journal and thus it will contribute to the researchers to enhance the knowledge /information about the kind of study being published in this journal in last ten years
Immunohistochemical expression of Bcl-2 in benign and malignant salivary gland tumors
Objectives: The present study was undertaken to assess and compare the immunohistochemical expression of Bcl-2 in selected benign and malignant salivary gland tumors. Study Design: A total of 50 cases of buffered formalin-fixed, paraffin embedded tissues of previously diagnosed cases of benign and malignant salivary gland tumors from the archives of Department of Oral and Maxillofacial Pathology and Microbiology, SDM College of Dental Sciences and Hospital, Dharwad, India, were taken for the study. The immunohistochemical staining procedure was performed using monoclonal anti Bcl-2 antibody, as directed by the manufacturer. Results: Thirty six cases (72%) out of 50 cases showed a positive expression for Bcl-2. Benign salivary gland tumors showed a positive expression in 8 out of 14 cases (~57%) and malignant salivary gland tumors in 28 out of 36 cases (~78%). The staining was intense in the normal lymph node, which is used as a positive control. Bcl-2 expression was seen in both benign and in malignant salivary gland tumors taken for the study except in "canalicular adenoma". Conclusion: The immunohistochemical expression of Bcl-2 was greater and more intense in malignant salivary gland neoplasms, suggesting a high survival rate of tumor cells in malignant neoplasms. © Medicina Oral S.

Key Determinants of Sustainable Product Design and Manufacturing
AbstractIn the present era, there is an urgent need to make all industrial products sustainable for reduce environmental impact in the Production and consumption. Sustainable manufacturing is becoming crucial for businesses more than ever before. In this context, The key determinants of sustainable Product Design and manufacturing (SPDM) has been examined in the form of Environmental, Economical and Social factors in the Indian manufacturing organisations which provides the basis of SPDM for Indian manufacturing firms. This paper identified the various types of key determinants of Sustainable Product Design and Manufacturing (SPDM) by the survey methodology. A survey is conducted to confirm the key determinants in Indian manufacturing organisations. From this study it is proposed that the more emphasis should be given on Product life cycle, 6R (reuse, recover, recycle, redesign, reduce and remanufacture) and Housing and service infrastructure for this the new tools and techniques will be develop for creating a sustainable product. In this regards, it is suggested that proposed key Determinants play a vital role in product design and manufacturing and gives the better approach for sustainability
Performance of a Community-based Health and Nutrition-education Intervention in the Management of Diarrhoea in a Slum of Delhi, India
Diarrhoeal infections are the fifth leading cause of death worldwide and continue to take a high toll on child health. Mushrooming of slums due to continuous urbanization has made diarrhoea one of the biggest public-health challenges in metropolitan cities in India. The objective of the study was to carry out a community-based health and nutrition-education intervention, focusing on several factors influencing child health with special emphasis on diarrhoea, in a slum of Delhi, India. Mothers (n=370) of children, aged >12–71 months, identified by a door-to-door survey from a large urban slum, were enrolled in the study in two groups, i.e. control and intervention. To ensure minimal group interaction, enrollment for the control and intervention groups was done purposively from two extreme ends of the slum cluster. Baseline assessment of knowledge, attitudes, and practices on diarrhoea-related issues, such as oral rehydration therapy (ORT), oral rehydration salt (ORS), and continuation of breastfeeding during diarrhoea, was carried out using a pretested questionnaire. Thereafter, mothers (n=195) from the intervention area were provided health and nutrition education through fortnightly contacts achieved by two approaches developed for the study—‘personal discussion sessions’ and ‘lane approach’. The mothers (n=175) from the control area were not contacted. After the intervention, there was a significant (p=0.000) improvement in acquaintance to the term ‘ORS’ (65–98%), along with its method of reconstitution from packets (13–69%); preparation of home-made sugar-salt solution (10–74%); role of both in the prevention of dehydration (30–74%) and importance of their daily preparation (74–96%); and continuation of breastfeeding during diarrhoea (47–90%) in the intervention area. Sensitivity about age-specific feeding of ORS also improved significantly (p=0.000) from 13% to 88%. The reported usage of ORS packets and sugar-salt solution improved significantly from 12% to 65% (p=0.000) and 12% to 75% (p=0.005) respectively. The results showed that health and nutrition-education intervention improved the knowledge and attitudes of mothers. The results indicate a need for intensive programmes, especially directed towards urban slums to further improve the usage of oral rehydration therapy
Oxide Nanostructures: Characterizations And Optical Bandgap Evaluations Of Cobalt-Manganese And Nickel-Manganese At Different Temperatures
Cobalt-Manganese and Nickel-Manganese oxide (CoMnO and NiMnO) nanoparticles were prepared by chemical co-precipitation method by decomposition of their respective metal sulfides and sodium carbonate using ethylene diamene tetra acetic acid as the capping agent. The samples were heated at 400, 600 and 800 °C. The average particle sizes were determined from the X-ray line broadening. The diffractograms were compared with JCPDS data to identify the crystallographic phase and cubic structure of the particles. The samples were characterized by XRD, FTIR and UV analyses. The internal elastic micro strains were calculated and it was seen that as the particle size increases strain decreases. The FTIR studies have been used to confirm the metal oxide formation. The chemical compositions of the samples were verified using EDX spectra. The surface morphologies of the samples were studied from the SEM images. The absorption spectra of the materials in the UV-Vis-NIR range were recorded. From the analysis of the absorption spectra, the direct band gaps of the materials were calculated.

Association of sociodemographic characteristics with KAP regarding menstrual hygiene among women in an urban area in Delhi
Introduction: Menstruation despite being a natural process is linked with several misconceptions and false practices, which sometimes results in adverse health outcomes. The aim of this study was to assess knowledge, attitude, and practices regarding menstrual hygiene and their association with sociodemographic determinants among women in an urban area of Delhi.Materials and Methods: A community‑based cross‑sectional survey was conducted for a period of 1 year among 350 women age 18–45 years residing in an urban resettlement colony in Delhi. Semi‑structured questionnaire containing questions regarding subject’s demographic profile, their knowledge, attitude, and practices pertaining to menstrual hygiene was used. It had seven questions regarding knowledge and eight questions each about attitude and practices regarding menstrual hygiene, respectively. A 5‑point Likert scale was used to assess women’s responses to attitude questions. Practices satisfactory or unsatisfactory were based on UNICEF guidelines. Data were analyzed using SPSS software version 17.Results: The mean age of women was 26.53 ± 0.295 years. More than three‑fourths (88.3%) women had good knowledge, whereas only 32.3% of women had a positive attitude regarding menstrual hygiene. More than two‑thirds of the women were using sanitary pads as menstrual absorbent. Significant association was seen between knowledge and subject’s marital status (P = 0.034) and subject’s occupation (P = 0.046). A significant association was observed between attitude and socioeconomic status of the participant (P = 0.001).Conclusion: These findings indicate the need for education about healthy menstrual practices. Health education is an essential requirement to fill the knowledge gap to promote accessibility, availability, and sanitary facilities and products.Keywords: Attitude; knowledge; menstrual hygiene; practice
